Nope, the rubbing was either the nose of the t-arm (when the exhaust heats the poly bushings and get them from rock hard to softer, and has been that in the past...), but in this case it was the parking brake cables, the "fulcrum" parts in the back...
I am rebuilding the t-arm this year to a twin beam and making a stronger H-bracec for the nose, and will be addressing these issues oncee and for all this winter.
